Product Description
3. To determine the content of nitrate ions in mountain water by the potentiometric method, standard solutions were prepared and their potential difference was measured:
pNO3 1.0 2.0 3.0 4.0 5.0 6.0
E, mV 493 404 315 226 137 48
Determine the molar concentration of nitrate ions in the analyzed sample with a potential difference of 373.2 mV.
